STUMP-PULLER.

SPECIFICATION forming part of Letters Patent No. 328,720, dated October 20,1885.

Application filed August 29, 1885. Serial No. 175,623. (No model.)

Toall whom it may concern:

Be it known that I, \VILHELM Scnusrna, of Medford, in the county of Taylor, and in the State of \Visconsin, have invented certain new and useful Improvements in Stump-Pullers; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to stump-extractors; and it consists in the construction and arrangement of the several parts,as will be fully described with reference to the accompanying drawings, in which- Figure l is a perspective view showing my stump-extractor in operative position; Fig. 2, a sectional plan View through line 00 cc, Fig. 3; Fig. 3, a front elevation, partly in section; Fig. 4, a detail view of connecting-rods and their coupling-shackle, and Fig. 5 a top plan View of the shaft-head.

In the drawings is represented a supportingframe having vertical standards a a, united by horizontal cross-pieces b I), the lower one, b,of these cross-pieces having a greater width than the upper one, and formed with a central circular opening to receive the foot of and act as a bearing for a shaft or drum, A, the bearing for the upperportion of said drum or shaft being formed by half-circular openings respectively cut in the upper cross piece, b, and an auxiliary cross-piece, c, the latter being supported by brackets c c, bolted to the vertical standards a a,and coining flushagainst the former.

Secured by hooks d or other suitable means to lhe forward portion of the supporting-frame is a guideway, O, in which travelsa block, D, having therein grooved pulleys or sheaves d dfland provided at its front end withatongue, (1 to receive the shackle E of a connecting rod, F, said shackle preferably consisting of a single piece of metal cast or swagcd out so as to have a central web and U-shaped ends,the latter provided with openings to receive a pin or bolt by which the coupling is completed.

Secured on the lower horizontal crosspiece, b, and against the vertical standards a a, are blocks 6 c, to the upper faces of which blocks are pivotally fastened spring-pawls ff, which engage notches g g, cut in the lower portion of the shaft or drum A, and a binding-ring, G,

which ring encircles said shaft or drum, and in connection with its cutaway portion or lower journal, 71, of the latter forms a shoulder, against which rests the rear end of a lever,H, fulcrumed at h to the lower cross-piece, b.

The upper portion of the shaft or drum A is cut away to form a journal, h and shoulder h", said journal bearing in the circular opening formed by the cut-out portions of the crosspieces I) c.

Above the upper journal portion of the shaft A, and formed integral therewith, is a tenon, I, and short shaft 2', as more clearly illustrated by Fig. 5, said short shaft having cut therein a slot for the reception of a key, i, the latter suspending the main shaft or drum in operative position. The tenon I is designed to fit a correspondingly-fornied mortise in the block K upon the under side of atongue, L, and in terposed between the said block and the crosspieces I) c of the supporting-frame is a loose collar, It. To the forward sides of the crosspieces I) b are secured uprights Z Z, the former being slotted near its lower end to receive a pulley, in, set in a stirrup, m, said stirrup being fitted in the upright, so that the inner faces of its sides are flush with the inner faces of the slot in said upright, and act as a guide for the drawing-rope.

Secured to a hanger, it, upon the top of the upright Z is a cord, which passes down under a pulley in the top of a traveler-frame, M, then up over and down from a pulley, 0, setin a slot in the upper end of the upright K, said cord having secured to its free end a weight, 0, said traveler-frame operating in guides Z Z. The lower portion of the traveler-frame has journaled therein a pulley, p,over which travels the drawing-rope N, which is secured at one end to the cross-piece b by a socket, r, and eyebolt r, the latter being driven in said cross-piece, as shown by dotted lines in Fig. 2. The free end of this rope N is passed under and over the pulley d in the block D, thence back over and under the pulley in, secured in the slotted upright Z, then forward under and over the pulley d in said block D, then back over the pulley p in the traveler-frame M, and made fast to the shaft or drum A.

The tongue L is braced at its rear end by longitudinal pieces 3 s, bolted thereto, and furas the .former comes in.

object by means of achain passed through.

eyes formed by the bends in stay-rods'B'R, which rods have their ends connected by links and eyebolts to the rear end of said support-;

ing-frarne. The pulley-block D being run out upon the guideway G and the rope N almost or entirely unwound from the shaft or. drum A, a coupling-rod, F, is then united by the shackle E to the tongue (1 0f said pulley-block,

and a chain, S, secured to an eye in the forward end of this coupling-rod'is thrown around the'stump tobe extracted. Where the stump orustumpsto be extracted. are at-a distance fcomthe extractor, connectionis made by splicinga sufficient number of the rods F by means of shackles E, as shownin Fig. 4. The tongue L beingrotated, the shaft or drum A, keyed and-suspended to saidtongue, is revolved, and

the-rope N, winds thereon, andvthe bloclcD, made fast to the stump through the medium of -its tongue d? and the connecting'rod' or rodseF and chainS, travels back on the guideway -G. As this operation is continuedgreat force is exerted against. the stump tofinally draw it up out .of theground. The weighted traveler Mguides the rope N and causes it to wind in even coils upon the shaft or drum. Saidrope being slightly heavier than the counter-weight o, the latterv is gradually drawn up As the shaft 'ordrum is revolved in a direction to wind the rope the springrpawls f f, which are rounded upon their outer forward .ends, slipin and out of thenotches g g in said shaft, these notches being also rounded upon one of their side faces to permit the play of the pawls. The inner faces of thelpawls and their opposing faces in the notches are squared, so as tohold and pre:

vent a reverse motion of the shaft or drum should a break occur or it be found desirable at. anytime to discontinue the operation of the extractor.

After the stump has been extracted, and it is desired to repeat the operation above described, the key vl, which suspends the main shaft or drum inoperative position, is'withdrawn and. the latter revolved enough to dis engage thespring-pawls. This operation being accomplished, the main shaft or drum will 1 of its own gravity dropdown until the shoulder formed by its lower cut-aw ay portion, h,and thebinding-ring G rests against the rear end i ofthe lever H, interposed between the binding-ring G and the lower cross-piece, 1).

its mortise in the rear portion of the tongue L, saidvtongue then resting upon the loose ring k, which ring is now occupied by the tenon, and the mortise by the short shaftvt', which shaft revolves freely. therein. The tongue and shaft being now disengaged, the block D can be drawn out upon its guideway By I this operation the tenon I is disengaged from ,i

O and the ropeunwound from its drum withoutidanger of said tongue swinging around against the operator. To re-engage the tongue and shaft or drum, the lever H, fulcrumed at h, is depressed, so that its rear end,which rests under the shoulder h, will raise said shaft orv drum to the position shown in Figs. 1 and 3. The key i is now placed in the slot 'of the short shaft 2', and the machine is thus .made ready for another operation, the entire process occupying but a brief time in its accomplishment.

To entirely disconnect the shaft or drum A fromthe supporting-frame, the upper auxiliary cross-piece, c, is removed, when said shaft or drum can belifted from its bearings, the tongue L. being first disengaged and lifted .off from the shaft or drum-head.

Havingthus fully described my invention,

what I claim as new, and desire to secure-by Letters Patent, is
